Hello Simon,

I do see the output 'AWAKE' through the COM port. I am also measuring the P0.01 pin with a scope probe and it always stays low. How can I reroute to the GPIO instead?

Best regards,

Varouzan

I tested your example, and was able to see the output ("AWAKE"), which means the TX pin is not low all the time. Are you able to see the serial output? How did you measure it? If you are measuring on P0.01 on the DK you will not see the activity on the TX pin, since the GPIO is routed to the interface MCU instead.

Best regards,

Simon
